Regarding trans: I get the sports thing (I went through most of my male puberty, so I still have some residual advantages from it, probably), but I don't get the bathroom thing. What difference does it make if I piss in the ladies' room instead of the men's room? I'm planning on getting rid of my penis someday; what good would it do for a post-op trans woman (who fits the simplest, most easily observable biological reality: the Kindergarten Cop rule) to piss next to dudes?
Since Motorcity is still responding to this thread, these weren't rhetorical questions.
